Patent DE-4305184-A1 (DE)
Title: Device for receiving a normal-time transmitter for an extended temperature range
Inventor: ROTH HEINZ-JUERGEN
IPC: H04B1/18
Filed: 1993-02-19
Abstract: To enable reception of normal-time transmitters, the field strength produced by the normal-time transmitter at the reception location needs to be converted, using a resonant antenna circuit, into electrical current and voltage values, thereby enabling further amplification. The device according to the invention enables optimum reception sensitivity to be maintained, even when significant changes in ambient temperature occur at the reception location, For narrowband filtering, crystals are used which are tuned to the frequency of the normal-time transmitter and which provide selective processing of the received signal in the integrated receiver. The crystals undergo a temperature drift. This temperature drift is prevented in that, along with blocks of circuits for processing the normal-time signal, a temperature controller is provided in the integrated receiver which heats the crystals located immediately adjacent to the IC, thereby eliminating the unwanted temperature drift of the crystals. The clock industry is a potential user of the device according to the invention. It is of particular interest to motor vehicle supply companies.
Patent DE-4306414-A1 (DE)
Title: Lead-metering valve
Inventor: HINTZ ULRICH
IPC: B22D41/16
Filed: 1993-03-02
Abstract: A valve for the precise metering of liquid lead into moulds, e.g. for battery electrode grids, comprises a valve tappet which can be moved up and down and at the end of which a cylindrical pin (29) is integrally moulded on, as well as an outflow opening (27) corresponding to the pin and located in the bottom of a lead storage vessel as a valve seat, through which opening the pin penetrates in the closed position. In this arrangement, owing to a reduction in diameter of the pin by about 0.04 mm with respect to the diameter of the hole, a narrow annular gap remains open between said opening and the pin, into which molten lead (30) seeps. In this way, the valve forms a seal over the entire circumferential surface of the cylindrical pin, and the oxidation of the lead is also utilised. <IMAGE>

Title: Device for controlling a window wiping system
Inventor: REIME GERD
IPC: G01N21/55
Filed: 1994-04-06
Abstract: In a device for controlling a window wiping system, a sensor device (12) is arranged in the wiping area (10a) of a wiper, which sensor device (12) is passed over by the wiper during a wiping process. A counting arrangement (15) is provided whose counter counts the signals Es conveyed by the sensor device (12) during a wiping process as a means for detecting the signals produced by the sensor being passed over, a specific value of the counter (Z) being exceeded triggering a further wiping process. This value is at least larger than the number of signals which are produced by the sensor device (12) while the wiper is passing over. In this arrangement, a switching contact device (14) resets the value of the counting arrangement to an initial value as soon as the wiper is in a position assigned to the switching contact device (14). By means of this arrangement, control of a window wiping system can be realised in a simple and cost-effective way (Fig. 1). <IMAGE>

Filed: 1994-05-17
Abstract: In a production instrument for semiconductor devices for forming silicon oxide films by the CVD method under low pressure, anhydrous HF gas and inter-halogen compound gas are introduced together with carrier gas into a reaction chamber or into a vacuum evacuation tube. The anhydrous HF gas and the inter-halogen compound gas react to form deposits which adhere on to the internal wall of the reaction chamber or of the vacuum evacuation tube, so that the deposits decompose into gases and are removed. This prevents particles originating from the deposits from being taken up by semiconductor wafers.

Title: Circuit arrangement for a demodulator of a radio data signal in a broadcast receiver
Inventor: VOGT LOTHAR DR
IPC: H04H20/00
Filed: 1994-06-03
Abstract: In a circuit arrangement for a demodulator of a radio data signal in a broadcast receiver, the multiplex signal is mixed in digital form into the baseband into two phase angles shifted through 90 DEG  in relation to one another using a reference carrier obtained from a sampling clock generated in the broadcast receiver, thereby producing a first and a second composite signal. A first and a second auxiliary signal are generated with a sinusoidal and a cosinusoidal characteristic. The first composite signal is multiplied by the first auxiliary signal and the second composite signal is multiplied by the second auxiliary signal, the results of these multiplications being added together with the formation of a first output signal. The first composite signal is multiplied by the second auxiliary signal and the second composite signal is multiplied by the first auxiliary signal, the results being subtracted from one another with the formation of a second output signal. The phase angle of the auxiliary signals is controlled in such a way that the first output signal corresponds to the radio data signal reduced into the baseband.
